CSFK CSI SZEMINÁRIUM / KONKOLY OBSERVATORY SEMINAR

Date: Mar 05 (Thursday) 14:00


Jose R. Bermejo (Konkoly Observatory, Hungary):

Towards a precise determination of primordial non-Gaussianity with current 
and future galaxy surveys
In the decade of large-scale structure (LSS) surveys, we are creating the 
largest and most precise ever 3D maps of the Universe. These surveys will 
help us to better understand dark energy, but they are also providing a 
cosmic window to the physics of the primordial Universe. In particular, an 
open question in cosmology is to determine the nature of the cosmic inflation 
period. Some of the inflationary models proposed in the literature predict 
that the initial conditions of the Universe should follow Gaussian 
statistics, while others predict non-Gaussian conditions that can be 
accounted for through the so-called 'primordial non-Gaussianity' parameter. 
Measuring primordial non-Gaussianity is one of the hot topics in LSS 
cosmology, since it allows us to confirm or rule out inflation models. In 
this talk, I will review the current status of the measurement of primordial 
non-Gaussianity with LSS surveys and elaborate on the next steps, techniques 
and methods to achieve better estimations
  in the next few years.
